Abstract

The invention relates to a left-turn-free flyover, comprising an intersection flyover and a turn-around flyover. The left-turn-free flyover comprises the intersection flyover, a connecting bridge and the turn-around flyover, wherein left-turn vehicle traffic can be concealed at an intersection; right-turn canalization distribution is carried out. Thus, mutual interference of turning vehicles and straight vehicles is greatly reduced; a traffic accident is greatly reduced; the traffic control power is also saved.

Description

A kind of without left-turn flyover
Technical field
The present invention relates to a kind of overpass bridge of urban road, it is current that left turning vehicle can be cancelled in intersection, make it carry out the shunting of right-hand rotation canalization, right-hand rotation vehicle pass-through is realized canalization shunting, greatly reduce the turning vehicle of intersection, two road and through vehicles, non power driven vehicle and pedestrian's phase mutual interference, and at least realize a through vehicles barrier free accessibility on road, can effectively solve motor vehicle crossing traffic congestion problem.
Background technology
In Current City Road traffic, crossing arranges between the motor vehicle that traffic lights regulate each flow direction more, respectively flows between motor vehicle and bicycle and pedestrian and influence each other, and easily causes and blocks up and have an accident, and the traffic efficiency of road traffic is lower.Other urban road crossing shunting mode also has larger defect: rotary island has been split into city embolism; The overpass bridge that is provided with at crossing also having regulates shunting, but the large multiple footprint of overpass bridge is excessive, and cost is also too high, and long construction period is not suitable for arranging in urban road; The construction also having viaduct, its cost is higher, construction period is longer, is not particularly suitable for equally improving existing urban traffic conditions.
Summary of the invention
In order to overcome the shortcoming of prior art, the invention provides a kind of overpass bridge, make intersection can cancel left turning vehicle current, carry out the shunting of right-hand rotation canalization, right-hand rotation vehicle pass-through is realized canalization shunting, greatly reduces the phase mutual interference of turning vehicle and through vehicles; And realize the through vehicles barrier free accessibility at least one road, greatly reduce influencing each other of turning vehicle and bicycle and pedestrian, reduce turning vehicle and other vehicle, bicycle and pedestrian's traffic accident, motor vehicle crossing traffic congestion problem can be effectively solved, urban highway traffic traffic efficiency can be greatly improved.
The present invention solves the technical scheme that its technical problem takes: comprise crossing overpass, connecting bridge and tune overpass bridge.
1), the present invention can make urban road crossing cancel the present invention has following advantages:, left-hand bend vehicle realizes by tune overpass bridge the object that shunting reaches left steering, and that has avoided that left-hand bend vehicle causes blocks up and the generation of accident; 2), right-hand bend vehicle realized and being turned right by the built on stilts circle bridge of turning right, and reduced and the bicycle of nonmotorized vehicle lane and pedestrian's phase mutual interference, reduced the generation of traffic accident, reduced the jam that right-hand bend vehicle causes; 3), turning vehicle because of its tune turning process be to complete on the circle bridge of two kinds of overpass bridges or turning platform, therefore its only affect the straightgoing vehicle in this track and turn after be incorporated to the straightgoing vehicle to track, through vehicles must be through a slope; 4) if traffic rules regulation bicycle and pedestrian are all current in ground, the motor vehicles of keeping straight on a road and non power driven vehicle and pedestrian are unblocked, and the motor vehicles of keeping straight on an other road and non power driven vehicle and pedestrian need to regulate through traffic lights current.5) if traffic rules regulations wherein across an other road flyover on establish nonmotorized vehicle lane and pavement, the equal barrier free accessibility of the through vehicles on two road, but the vehicle of turning right need to be dodged with bicycle and pedestrian on flyover, need to regulate voluntarily or traffic lights adjusting.6), simple in structure, small volume, cost is few, can extensively promote the use of.
